题意:给定三维数组,0表示正常,1表示有肿瘤块,肿瘤块的区域>=t才算是肿瘤,求所有肿瘤块的体积和 这道题一开始就想到了dfs或者bfs,但当时看数据量挺大的,以为会导致栈溢出,所以并没有立刻写,想有没有别的办法.然而结果是,实在想不出别的办法了,所以还是尝试写写dfs.bfs. 一开始先用了dfs,最后两个样例段错误,估计是栈溢出了.之所以dfs栈溢出,因为dfs的时候每个状态都会存储在堆栈里,就好比dfs的第一个状态,一直保存到最后整个dfs结束.而bfs是存储在队列中,每次队列都会有状态取…

1085 Perfect Sequence (25 分) Given a sequence of positive integers and another positive integer p. The sequence is said to be a perfect sequence if M≤m×p where M and m are the maximum and minimum numbers in the sequence, respectively. Now given a seq…
Knight Moves A friend of you is doing research on the Traveling Knight Problem (TKP) where you are to find the shortest closed tour of knight moves that visits each square of a given set of n squares on a chessboard exactly once. He thinks that the m…
1103 Integer Factorization(30 分) The K−P factorization of a positive integer N is to write N as the sum of the P-th power of K positive integers. You are supposed to write a program to find the K−P factorization of N for any positive integers N, K an…

一门武功能否传承久远并被发扬光大,是要看缘分的.一般来说,师傅传授给徒弟的武功总要打个折扣,于是越往后传,弟子们的功夫就越弱-- 直到某一支的某一代突然出现一个天分特别高的弟子(或者是吃到了灵丹.挖到了特别的秘笈),会将功夫的威力一下子放大N倍 -- 我们称这种弟子为"得道者". 这里我们来考察某一位祖师爷门下的徒子徒孙家谱:假设家谱中的每个人只有1位师傅(除了祖师爷没有师傅):每位师傅可以带很多徒弟:并且假设辈分严格有序,即祖师爷这门武功的每个第i代传人只能在第i-1代传人中拜1个师…
